#617 Umit hanged when "Quick and verbose scan"

[Haoyu Bai]

I checked out the svn head (rev.2911), start Umit directly in the source tree. My system is Archlinux.

Some systmen info:

$ cat /proc/version
Linux version 2.6.24-ARCH (root@artin) (gcc version 4.3.0 (GCC) ) #1 SMP PREEMPT Sun Mar 30 11:40:06 CEST 2008

$ python -V
Python 2.5.2

Psyco not installed.

I use KDE as desktop evnironment.

Reproduce the problem:

1. start Umit
2. choose "Quick and verbose scan" in Scan profile
3. I choose my local subnet as target (10.85.11.0/24)
4. Press "Scan"
5. Umit GUI hanged, from top we can see that umit using more than 50% CPU, and the Nmap process already exited.

strace shows that Nmap stall on a brk() system call.
